Ajahn Brahm reinterprets the Buddhist principle of “viriya” – often interpreted within Buddhist schools as being “energy” or “effort” – by point out that the root of the work “vira” means “hero”, and that we can interpret “viriya” (which is one of the Seven Factors of Enlightenment”) as “heroism” or “courage”. It’s this attitude of courage that can help us to face and overcome many of life’s challenges.
